Ruvara rwepombi dzesimbiinowanzoenderana nekushandiswa kwavo, anti-corrosion kurapwa kana indasitiri zviyero. Nyika dzakasiyana uye maindasitiri anogona kunge aine zvinodiwa zvemavara kuti ave nechokwadi chekuchengetedza, kusaora kana kusaziva zviri nyore. Izvi zvinotevera rondedzero yakadzama:
1. General zvinoreva DINSEN SML Pipe ruvara
·Dema/ grey/Yekutanga simbi yakakandwa kana asphalt/anti-corrosion coating Drainage, tsvina, mapaipi emanisipala
·Tsvuku/Mapaipi emoto, kupikisa kwekushisa kwepamusoro kana zviratidzo zvakakosha/Moto system, high pressure water supply
·Girinhi/Mapombi emvura ekunwa, machira ane hushamwari kwezvakatipoteredza (senge epoxy resin)/Mvura yepombi, mvura yegiredhi rekudya
·Bhuruu/Mvura yeindasitiri, mhepo yakamanikidzwa/Factory, compressed air system
·Yero/Mapaipi egasi (isina kukanda simbi, kazhinji mapaipi esimbi)/Kufambisa gasi (dzimwe nzvimbo dzichiri kushandisa simbi yakakandwa)
·Sirivha/Galvanized anti-rust kurapwa/Kunze, hunyoro nharaunda, yakakwirira corrosion resistance zvinodiwa
2. Zvinodiwa zvakakosha zvekukanda simbi pombi mavara mumisika yemumba uye yekunze
(1) Chinese musika (GB chiyero)
Drainage Cast Iron Pipes: kazhinji dema (asphalt anti-corrosion) kana yekutanga iron grey, yakavharwa ne epoxy resin (girinhi).
Kugovera Mvura Kukandira Iron Pipe:Yakajairika cast iron pipe: dema kana tsvuku (yekudzivirira moto).
Ductile Iron Pipe (DN80-DN2600): rusvingo rwekunze rwakapfapfaidzwa ne zinc + asphalt (dema), mukati memba ine simende kana epoxy resin (grey / girini).
Moto Dziviriro Pipe: tsvuku tsvuku, inoenderana neyakagadziriswa yekudzivirira moto yeGB 50261-2017.
Gasi Pipe: yero (asi mapaipi egasi emazuva ano anonyanya kugadzirwa nePE kana pombi dzesimbi, uye simbi yakakandwa haiwanzo kushandiswa).
(2) Musika weUS (AWWA/ANSI Standard)
AWWA C151 (ductile iron pipe):
Rusvingo rwekunze: kazhinji dema (asphalt coating) kana sirivha (galvanized).
Inner lining: simende dhaka (grey) kana epoxy resin (girinhi / bhuruu).
Moto Dziviriro Pipe (NFPA yakajairwa): dzvuku logo, mamwe anoda mazwi ekuti "FIRE SERVICE" kuti adhindwe.
Pipe Yemvura Inonwa (NSF / ANSI 61 certification): iyo yemukati lining inofanirwa kusangana nehutsanana zviyero, hapana chinosungirwa chinodiwa kune yekunze madziro ruvara, asi girini kana yebhuruu logo inowanzoshandiswa.
(3) Musika weEurope (EN chiyero)
EN 545/EN 598 (ductile iron pombi):
External Anticorrosion: zinc + asphalt (dema) kana polyurethane (girinhi).
Inner Lining: simende dhaka kana epoxy resin, isina kuomarara kwemavara mirau, asi inofanirwa kuenderana nemiyero yemvura yekunwa (yakadai seKTW certification).
Moto Pipe: tsvuku (dzimwe nyika dzinoda kudhinda "FEUER" kana "MOTO").
Industrial Pipe: inogona kunge iri yebhuruu (yakadzvanywa mweya) kana yero (gasi, asi pombi dzakakandwa dzesimbi dzakatsiviwa zvishoma nezvishoma).
(4) Musika wekuJapan (JIS chiyero)
JIS G5526 (ductile iron pombi): Rusvingo rwekunze runowanzo dema (asphalt) kana galvanized (sirivha), uye mukati memukati simende kana resin.
Moto pombi: kupenda tsvuku, zvimwe zvinoda kudhinda "kurwa moto".
Pombi yemvura yekunwa: yegirini kana yebhuruu lining, inoenderana neJHPA standard.
3. Kupesvedzera kwemuvara weakakosha anti-corrosion coatings
Epoxy resin coating: kazhinji girini kana bhuruu, inoshandiswa kune yakakwira anti-corrosion zvinodiwa (semvura yegungwa, indasitiri yemakemikari).
Polyurethane coating: inogona kunge yakasvibira, yakasviba kana yero, ine yakasimba yemamiriro ekunze kuramba.
Zinc + asphalt coating: dema rekunze madziro, akakodzera kuvigwa mapaipi.
4. Pfupiso: Ungasarudza sei ruvara rwepombi dzesimbi dzakakandwa?
Sarudza nekushandisa:
Drainage/sewage → dema/grey
Mvura yekunwa → girini/bhuruu
Kudzima moto → tsvuku
Indasitiri → nekuzivikanwa kwepakati (seyero gasi, bhuruu yakamanikidzwa mweya)
Sarudza nechiyero:
China (GB) → dema (mvura), tsvuku (kudzimisa moto), girini (mvura yekunwa)
Europe neUnited States (AWWA/EN) → dema (anti-corrosion yekunze), girinhi/bhuruu (lining)
Japan (JIS) → dema (madziro ekunze), tsvuku (kudzimisa moto)
Kana iwe uchiri kuziva nzira yekusarudza, ndapota taura naDINSEN
